The WS Reaslistic water is an acrylic based product and won't hurt the foam. My only problem w/ the product is that it needs to be "layered" in thin pours for any build up and can take a considerable amout of time to dry/ clear. The final leveled out surface is still somewhat soft and can shrink over time. It is OK for small creeks, puddles, mud holes drainage ditches, but have never had any great success w/ any larger pours. There are many other options as i venture others will propose. Actually Enviortex Lite works rather well and the "lite" version is not that "smelly". If you fear it will attack your foam base make sure it is well sealed and painted. You should be painting and basically detailing the water bottom anyway so don't worry about any problems.

Here is a question for scenery guru's.
My dinky layout uses blue foam (someother brands are pink and or yellow) insulating board, used on exterior walls of structures (prototype).
I have a corner spot, next to a hill, that is wide enough for a small width creek and or stream, around 1" wide, 1" deep and around 14" long.
Don't want to use resin, as this would melt the foam, a chemical reaction, plus the stentch associated with liquid resin.
Never have used the Subject product before.
From those with previous experience with this product, is this liquid safe to use on foam board, if you coat the surface with spackling compound (plaster) and once dry, painted water undersurface tones, etc. and pour product over this?
Being that this is such a small area to cover, thought that a Learning Kit for water, would be ideal, instead of buying seperate items to accomplish project.
What do you think?
